Answer 2

You in k12 right Geometry correct?

Answer 3

I can help. I did this last year.

Answer 4

right

Answer 5

okay ill give you an example and see if that helps.
Graph the image of the figure after a dilation with a scale factor of 1/4 centered at (5, −5)
The procedure to find each point is



[ Vertex point of triangle - dilation center ] * scale factor + dilation center



First point

[ (-3,7) - (5, - 5) (1/4) + (5, -5)

[ -8, 12)(1/4) + (5, -5)

(-2, 3) + (5, -5)

(3, -2)



Second point

[ (-7, -5) - (5, -5) ] (1/4) + (5, -5)

[ -12, 0 ] (1/4) + (5, -5)

(-3, 0) + (5, -5)

(2, - 5)



Last point

[ (9, 3) - (5, -5) ] (1/4) + (5, -5)

[ 4, 8] (1/4) + (5, -5)

(1, 2) + (5, -5)

(6, - 3)
